Martinez confirms Atletico deal

The La Liga club have agreed to Porto's £24.8m release clause and the Colombia striker will have some time off before heading for Spain to complete formalities on the deal.

The 28-year-old look destined for a switch to AC Milan earlier in the summer before a deal with the Serie A giants fell through.

"I can confirm I am going to Atletico," said Martinez after Colombia's Copa America defeat to Argentina in Vina del Mar on Friday night.

"I am going there for four years, but I still don't know when I will be introduced.

"It's all ready. I'm going to enjoy spending some time with my family for now and then travel to Spain to introduce myself to my new club," said Martinez after Colombia's 5-4 defeat on penalties.

"I'm very excited about taking this step with Atletico Madrid. It's a new challenge in my career and I hope things turn out very well for me there.

"I'm joining with the promise of contributing to ensure the club follows their evolution."
